Original application filed July 1, 1920, Serial No. 393,397.V Dividedand this application filed November 29, 1920. Serial No. 427,170.

(GRANTED UNDER THE PROVISIONS 0F THE ACT OF MARCH 3, 1921, 41 STAT. L.,1313.)

To all w hom t may concern Be it known that I, HENRI CHAMBON, a citizenof the French Republic, and resident of Paris, France, haveinvented'certain new and useful Improvements in Envelopes for SendingPost Cards and the like, (for which I have filed applications inBelgium, May 2, July 15, and November 10, 1919; in France, March 7 and26, April 11, 19,19, and March 9, 1920; in Great Britain, Marchl 27,1919, Patent No. 138,752, and in Germany, December 18, 1919,) of whichthe following is a specification. Y i

The present invention, divided out from my application No. 393397 filedJuly 1, 1920, relates to paper sheets or blanks, which, owing to aconvenient folding, may contain one or more post cards and yet serve asletters.

lith this object in view the blank is conveniently cut out and providedwith openings or windows disposed in such a manner that one, two or morepost cards or the like, enclosed in the conveniently folded blank, arearranged so that the corresponding postage stamps may be canceledthrough the cut out windows and the characteristic feature of theinvention consists in that the cards are maintained in a fixed positionwithin the envelope by means of the integral flaps resulting from thecutting out of the windows. Furthermore a convenient folding and agummed iiap secures a perfect closure of the envelope, whereby neitherthe contained post cards or the like, nor the letter written on theblank, may be read by an unauthorized person.

In order to clearly explain the object of the invention, it will befully described hereinafter with reference to the accompanying drawings,in which:

Figs. 1, 2 and 3 show a combined letter and envelope having openings orwindows, wherein the latter are utilized for arranging post cards or thelike in suitable positions, so that one, two or more stamps may be obliterated through corresponding windows, said post cards being alsoadapted to be held in position by small paper iaps resulting from thecutting out of the windows or by inserting the gummed strip intocorresponding` openings.

igs 4 and 5 show a combined letter and envelope wherein three post cardsare xedly held in position, the respective stamps of said post cardsbeing arranged side by side.

In Figures 1 to B, the blank is provided with suitable juxtaposed cutout openings 4, the corresponding flaps 5 of which, conveniently turnedinwardly, maintaining the post cards inserted within the envelopeletter, the first post card engaging the right hand flap 2 of theenvelope, the second post card engaging the bottom of the flap 5 of theright hand opening 4, the third postcard engaging the bottom of the flap5 of the adjacent opening 4 and so on, the stamps of said post cardsbeing thus placed side by side in said openings 4, whereby thecancellation of the stamps may occur without any difficulty. The portion3 of the letter envelope is folded upon the post cards. Small tongues 6formed on the outer longitudinal margin of said portion 3 may beinserted below the post cards by bending around the edge to hold samesecurely in place. Instead of said tongues I may provide cutawayportions, whereby the gummed flap 2 will be glued upon the front of thepost cards at the points where said cutaway portions are provided.

Figure 3 shows the front side of the envelope and the manner in whichthe stamps are placed. This form of envelope permits writing on the oneside of the paper sheet and at the same time three post cards or thelike may be inserted, the stamps of which are in front of the threewindows 4 on the front of the closed envelope and the latter isinviolably closed. Said envelope may also be provided withadvertisements on its inner as well on its outer face.

In Figs. 4 and 5 a letter card, the size of which is convenient tocontain three post cards in the positions which will ne described, hasone transverse margin 7 and the halves of the side margins 71 providedwith gum. Said margins are also provided with perforations to facilitatethe opening of the letter card. In the upper left hand corner I providethree openings or windows 4 spaced by narrow strips 8, and the two firstopenings are provided with iaps 5 integral with the blank. The edge ofthe first post card abuts against the gummed margin portion 71 of theblank, the stamp of said post card being then placed in the L firstopening 4, the second post card is shifted on the first one until theleft hand edge thereof engages the bottom or fold' of the first fla-p 5,the stamp of said second post card being then placed in the secondopening 4 and iinally the third post card is shifted on the second oneuntil itsV left hand edge engages the foldV of the second lap 5,Y

the stamp of said third post card being then placed in the third openingL The post cards being in these positions, the letter card may be closedlike the usual letter cards, whereupon the enclosed post cards arefurthermore lheld by the upper and. lower margins of the closed card.

It is obvious that, instead of three post cards, I maymake provisionsfor two postcards or only one post card, the device being'rformed withtwo or one opening respectively. The length of the sheet of paper willofcourse be varied -according' to the Vnumber yof post cards to beenclosed.

The Size of the blank depends upon the number of post cards with whichthe same is to be used, and suchV post cards may oi' V'course beinserted lengthwise or crosswise.

The usual combined letter blank and envelope is provided with thegumined rim portions l0, 11,'and l0 with such blank provided withwindows 4f. Post cards may be inserted, as described, or a letter sheetmayv be inserted, and in either event the stamp may .be aiiixed throughthe window Y Y onto the letter sheet and post cardl and'at the Sametimeonto the edge of thev blank about the'window, thus utilizing the stampas a means Vfor preventing abstraction of the post card or letter sheetwithout notice, which would necessarily result'from'the def struction ofthe stamp.

Having-now Jfully described my said invention, Vwhat'rI claim anddesirey to secure by Letters Patent, is Y Y A paper sheet or blank ofconvenient shape and dimensions, fold lines on lsaid blank for foldingsaine in shape of an -envelope, adjacent Vopenings or windows ofVsubstantially the size of a post stamp provided by cutting-the blank,the resulting flapsV remaining integral with lthe blankV by oneoi theiredges, said blank having tongues provided on the edge, said tongues,ai'ter'convenient foldingy of the blank, cooperating with'the windowliaps for' maintaining the inserted postcards or the like in a fixedposition withinY the envelope.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.

HENRI CHAMBON.
